Evidence for a chlorophyll a/b—protein complex associated with Photosystem II

AbstractA new chlorophyll a/b—protein complex designated as LHCPx was separated by SDS—PAGE. This complex differs from the light-harvesting chl a/b—protein of PS II, by its chl a/b ratio, its fluorescence properties and its apoprotein composition. Evidence is provided that this complex corresponds to a part of PS I antenna
